I've heard of zombie diodes, weird red ones that turned half laser half LED , but this honestly doesn't make any sense. If the laser overheated that bad and it went dead the only thing I can think of is the heat might of loosed the bond wire but those are so tiny there's no way it'd get back in place if the diode had one. Was it emitting any light? these 520nm diodes are kinda weird. I bet we're gonna find some interesting things about them.Also do the WLs of these drop when cooled or are they like 405nm lasers that hardly shift?

Wow. That's just... wow. Crazy how stuff like this happens, I once ordered a sample product from a Chinese company a very long time ago. It didn't arrive, so I just assumed it was a scam and moved on. 3 years later a small package shows up with the sample in it. I took me a few days to even figure out what it even was . As TLS already said, maybe it got sent to some laserist who just decided to fix it? Although unlikely, crazy stuff does happen.

Hmmm, well we are in Canada. Maybe customs opened it , trying to see how powerful a laser it is so they could confiscate it. The officer resolders some loose wire to check out the laser's power. Then, upon fluke chance, the officer in question had to go for a smoke break and another officer takes over. He figures it is broke , reseals the package with the newly fixed laser and sends it back to you. Sounds more plausible then random person fixing it. LOL

But would that really take a year? I mean I know Canadian post is slow, but... A year? And since when does customs have soldering stations for employees?

--> So after coming to an arrangement with the owner of LaserBTB, I sent it on its way to be replaced, only to find that through mistakes by both myself and the owner, that I sent it to an address that doesn't exist. <--

An LPF user, distraught at a burned out diode, packages it up for replacement. He thinks it's going back to its maker, but unbeknownst to him, by some trick of the zip code, is sending it into the postal district known as... the Twilight Zone

So, *ahem* what zip code does the Twilight Zone have? Care to share? I've got an old CNI I reversed polarity on that needs fixing.

Lol I used to love watching the twilight zoneas a kid! Thanks for the trip back to memory lane.
